The Dual Skins of a Media Façade: Explicit and Implicit Interactions.

In the fall of 2013, Mégaphone, an architectural-scale interactive "Speakers' Corner," was deployed outdoors after dusk in downtown Montréal, Canada. This urban art installation included a monumental media façade designed to display a transcription of some of the words uttered into the microphone by end users. Driven by the system's two temporal modalities--a performative "live mode" and an archival "sleep mode"--the video projections revealed the dual skins of a media façade that spanned almost an entire city block. This article examines how activists appropriated Mégaphone to transform an ordinary building into an urban mausoleum. [ABSTRACT FROM AUTHOR]
